Although sustaining physical injury in theater increases service members' risk for posttraumatic stress disorder (PTSD), exposure to explosive munitions may increase the risk of mild traumatic brain injury (mTBI). We hypothesized a higher incidence of PTSD and mTBI in service members who sustained both burn and explosion injuries than in nonexplosion exposed service members. ⋯ Given the high incidence of these disorders in burned service members, further screening of PTSD and TBI appears warranted. Because symptom presentation in PTSD and mTBI is clinically similar in acute and subacute stages, and treatments can vary widely, further research investigating symptom profiles of PTSD and mTBI is warranted.

Orthopedic injuries occurring in Operations Iraqi Freedom and Enduring Freedom (OIF/OEF) are complicated by infections with multidrug resistant bacteria. We describe demographics and microbiology of OIF/OEF casualties with primary and recurrent osteomyelitis. ⋯ The microbiology of osteomyelitis in veterans of OIF/OEF differs substantially depending upon whether the infection is new or recurrent. Gram-negative pathogens predominate early, being replaced with staphylococci after treatment, despite nearly universal use of gram- positive therapy.

Sepsis stimulates the sympathetic nervous system. The resultant elevation in plasma catecholamines, both norepinephrine and epinephrine (Epi), might be expected to alter the expression of inflammatory cytokines, which may directly or indirectly influence muscle protein balance. The purpose of this study was twofold: (1) determine whether Epi per se increases cytokine expression in skeletal muscle, and (2) determine whether beta-adrenergic blockade alters the sepsis-induced expression of inflammatory cytokines and mediators of protein balance in skeletal muscle. ⋯ These results demonstrate that although Epi is capable of increasing tissue cytokines in naive rats, inhibition of the beta-adrenergic effects of catecholamines exacerbates the sepsis-induced increase of selected inflammatory cytokines. This exaggerated tissue response is associated with alterations in muscle IGF-I protein and translation initiation, which would be expected to impair tissue protein synthesis.

Medicare and Medicaid Services (CMS) payment policies for surgical operations are based on a global package concept. CMS' physician fee schedule splits the global package into preoperative, intraoperative, and postoperative components of each procedure. We hypothesized that these global package component valuations were often lower than comparable evaluation and management (E&M) services and that billing for E&M services instead of the operation could often be more profitable. ⋯ Medicare's global surgical package underpays E&M services in trauma patients. In most cases, trauma surgeons would fare better by not billing for operations to receive higher reimbursement for E&M services that are considered "bundled" in the global package payment.

The opinion that injuries sustained in Iraq and Afghanistan have increased in severity is widely held by clinicians who have deployed multiple times. To continuously improve combat casualty care, the Department of Defense has enacted numerous evidence-based policies and clinical practice guidelines. We hypothesized that the severity of wounds has increased over time. Furthermore, we examined cause of death looking for opportunities of improvement for research and training. ⋯ In the time periods of the war studied, deaths per month has doubled, with increases in both injury severity and number of wounds per casualty. Truncal hemorrhage is the leading cause of potentially survivable deaths. Arguably, the success of the medical improvements during this war has served to maintain the lowest case fatality rate on record.
